One can safely say it’s an amazing lens. That particular design has been going on for almost 50 years, and it will easily be around for 100 more, if we judge by how many have been sold and in use worldwide. The V5 is still being offered by Leica and it’s the same optically as V4.
Some (a lot) might even prefer the V4’s handlng: a focus tab combined to a very short focus throw is really a Leica essence.
The “Tiger Paw” was coined by asians and indeed looks like their cartoon designs. No asian would ever think of a Beaver’s tail, and why would they? Do they even know what a beaver is, if not folklorically?
The V4 50 summicron is an extremely fine handling lens.
Optically it is Leica’s most enduring design ever.
Don’t listen to people who Yap and have very little experience.
